Trek Checkpoint SL 5 AXS Gen 3 2025

Description

The Checkpoint SL 5 AXS Gen 3 is an adventure-ready carbon gravel bike built to roll into the distant horizon. Its lightweight carbon frame is designed with comfort-focused geometry, room for beefy 50 mm tyres (as measured), and plenty of frame and fork mounts. Plus, IsoSpeed comfort technology helps soak up jarring road vibrations, helping you float over chatter and potholes. It comes equipped with a wireless 12-speed SRAM Apex XPLR AXS drivetrain to deliver plenty of gears for exploring the dusty road.

It’s right for you if…

You want a carbon gravel bike for exploring the beyond, and want to save on parts you can upgrade over time. You want the gravel-smoothing benefits of IsoSpeed tech that soaks up chatter from below so you can ride stronger for longer and plenty of mounts to carry all your gear and hydration.
